Openness and growth: what have we learned?

This paper discusses recent evidence regarding the existence of a cross-country empirical relationship between openness to international trade and economic growth. I discuss the empirical contributions of Warner (2003), Dollar and Kraay (2002), and Wacziarg and Welch (2003), and argue that these studies fail to convincingly establish a positive link between trade and growth. I also discuss the 1990-03 experience and show that growth does not display a significant correlation with any measure of trade openness over this period.
